Defense Area (Not ADIZ)

Asked by: 567 views
Airspace, FAA Regulations

What actions are required of a pilot when flying into a Defense Area?  I am familiar with the contents of Part 99 and the definition of a Defense Area.  But, I haven't been able to find what I would have to do.  I am not talking about crossing the border, just departing a US airport in Central TX and flying to an airport in SW TX (vicinity of Big Bend).  Thanks.

    The AIM says airspace in which the control of aircraft is required for reasons of national security. I would take that to mean you need to be in contact with the ARTCC and squawking the code they give you.

    But, I’m not a CFI, so I don’t know…… looking forward to finding out though!

    The answer is “whatever the FAA Administrator specifies”. So, it can be different for each area.

    It’s important for pilots to know and comply with the requirements before flying into the airspace. A good example would be the the Washington, D.C. area.

    The southern border with Mexico is part of the US Continuous ADIZ. Stay on the US side and there is nothing you have to do. Exactly what Defense area are you referring to?

    On the El Paso sectional, along the border, there is an area defined as “Defense Area” It has a thick, gray-ish gradient (i.e. not solid line) outline

    As I take a closer look, I see it extends all along the entire border. Maybe it is the ADIZ, but it just says Defense Area.

    Thanks for the replies. It is separate from the ADIZ, as the regs refer to them both separately. 99.7 refers to “special security instructions.” Just need to find out what those are. I appreciate the help.
